Glossary for Opuntia

associated media

A list (concatenated and separated) of identifiers (publication, global unique identifier, URI) of media associated with the Occurrence.

A description of the geographic distribution, or range, of the taxon. Includes descriptions of global, regional, or political aspects of range and whether the taxon is native or introduced in portions of the range and endemicity.

The geographic latitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are north of the Equator, negative values are south of it. Legal values lie between -90 and 90, inclusive.

The geographic longitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are east of the Greenwich Meridian, negative values are west of it. Legal values lie between -180 and 180, inclusive.

National Museum of Natural History, Smithsonian Institution (USNM), Washington, District of Columbia, USA. NMNH and USNM both refer to the National Museum of Natural History. Collections are associated with one or the other acronym. US, the US National Herbarium, is a collection within the National Museum of Natural History.

A specimen designated as nomenclatural type subsequent to the publication of the original description in cases where the original holotype, lectotype, all paratypes and syntypes are lost or destroyed, or suppressed by the (botanical or zoological) commission on nomenclature. In zoology also called "Standard specimen" or "Representative specimen". [Zoo./Bot./Bio.]

A list (concatenated and separated) of names of people, groups, or organizations responsible for recording the original Occurrence. The primary collector or observer, especially one who applies a personal identifier (recordNumber), should be listed first.

The full scientific name, with authorship and date information if known. When forming part of an Identification, this should be the name in lowest level taxonomic rank that can be determined. This term should not contain identification qualifications, which should instead be supplied in the IdentificationQualifier term.

The institution that holds a type specimen for a given species. The recommended best practice is to use the identifier in a collections registry such as the Biodiversity Collections Index (http://www.biodiversitycollectionsindex.org/).

Calculated as the volume of an ellipsoid, using the following equation: seed size = (4/3)π × (seed length/2) × (seed breadth/2) × (seed width/2). If only two dimensions were available, which was most often the case, breadth and width were treated as equivalent [seed size = (4/3)π × (seed length/2) × (seed diameter/2)2]. If only one dimension was given, then we used the volume equation for a sphere [seed size = (4/3)π × (seed length/2)3]. Where seed dimension could not be found, seed size was calculated from seed mass using the equation from Moles et al. (2005) and data from the same source papers as for animal × plant interactions, from a few related papers (Appendix S3) or from the Seed Information Database (SID) at the Royal Botanic Gardens, Kew (
